Dan, every day you CAN shovel snow is a GREAT day!

We have had some GREAT weeks haven't we.
Yes what you are describing sounds like thrush. Further the other things you are feeling sound familiar to me as well. So far I have been wrong about every one of those feelings!
Have all the "bad vibes" you wan't it will make the Doc's comments that much better when he/she says "everything looks great"
I can tell you I have been to the Doc at least 6 times when I was sure he was going to tell me the "bad" news. That pain or ache I was having was the real deal. Guess what? it didn't happen. These are very normal feelings and when mixed together with normal sensations, it is an instant awfulizer.
Take care
